My name is Paris Stalker (26), yes really, Paris Stalker…I’ve wanted to make games since I was 6.


Studied Game Design at Teesside University and won an award for Digital Creativity for making a game about Dementia.


Competed for a BAFTA nomination at the Dare to be Digital competition 2014, with an AR game called ‘Pygmy Panic’.


After a year of making simple mobile games with my younger brother, I decided I wanted to make something with more meat on it. A change of city, mild depression, a crushing part-time job and nearly 3 years later, here I am! Ready to show you what I got. Bring it!
